\\itlulra\ving thc water ot condeinattion from the condenser, and a eoiuhincd feed water heater and air separator T to which the water of condensation and the air or noii-c-onde-nsable gases withdrawn t'roln the condenser are delivered.

As illustrated. the heater consists ol' a receptacle provided with a port H through which watcr ot' coinlensation and the air or nolrcondellsahle gases withdrawn l'ronl the condenser are delivered. 'l`ln` receptacle is' also provided with an air vent. port 2L a water delivery port 1() and a port 1l through which au auxiliary supply olI water may he delivered'to the heater. 'l`he port i) is preferably located in the top ol the healer ca. ingr and the port S is located ahove the normal water lcvcl ol thc. heater and prefer-` ably in'onc side o1 the heater casing. ln the drawings I have Vshown a tray or trough 12 located within the casing for receiving the water delivered to the' heater lhrou,g rh

the port 11 and tordelircring thc., water in drops, thin streams or sheets to lthe bottom of the heater. rl`he bottom" "ot".y the tray is therefore ro\'ided with a series lit water delivery apertures 15'3, which ane arranged to deliver the water in drops. thin sheets-or streams through the. path `ol' lud entering the heater through thc Aport '.lhe tray may also lne-provided with air -vcnt apertures 14 for delivering to thc port 9 the. air which may be entraincd with the "ater entering the port 11. T

As illustrated, the air or non-condensable gast-.agarre withdrawn from the condenser hy means of'a steam actuated ejector-42 the inlet of which communicates with the air' otftake of-the condenser through a piping or passage 15 and the discharge of which communicates with the port. 8 of the heater through a pi-pe or passagol and a diffuser 16. The corrdensate discharge pump '5 communicates with the condensate ldischarge port of the condenser and is adapted to deliver 4the water of condensation withdrawn from the condenser to the discha-r e iping ot the ejector 4.. As illustrated, t e drhvcry piping 17 of the pump communicates with the annular delivery nozzle 18, located within the discharge Cpiping' of theV ejector, and arran ed to e iver the water, received by it,

to tie inlet end of the diffuser 16. The water delivery nozzle is preferably so arranged (SUN that the water issuing from it is delivered around a discharge nozzle 19, which comnumieates with the. exhaust. of the ejector 4:, and through which air or non-eolulensable l gases and st'ealn discharged from the ejector are delivered. With this arrangement. the water ol' condensation and the steam and air withdrawn from the ctmdenser are intimatt-lv mixtaLprior to or at the time of being delivered to the heater. In addition to this. the steam issuing from the ejector is vomit-maal by being brought into contact with the eooler water issuing trom the nozzle ts and eon'set|uentl \7 itimparts heat to the water. 'lhe intermiugling ot' the air and water also rauses the water to take up heat from the air and the air after being liberated in the heater 7 is discharged thereirom through the vent port t).

Une ol' the advantages ol' the invention is that substantially all the heat withdrawn troni the condenser is conserved and is dcliveretl to the t'eed water heater. In addi tion to this. the method employed for mixing the water with the heating steam largely eliminates the noise which is usuitlly eni-.ountered in 'feed water heaters. Another Jfeature. oi" the invention is that the nozzle' it) may he so constructed thatthe -fluid issuing therefrom into the diffuser 16 will exert an njeetor action on the water delivered ln the pump 5 and in this way aid the pump b v reducing the back pressure on it.

ln accordance with the United States patent statutes l have illustrated and described one embodimenty of" in v invention, but. I desire it. to he understood that various changes, modifications, substitutions, additions and omissions may be made in apparatus illus trate-d without departing from the spirit'. and scope of the invention as set. forth by the appended claims.

What I claim is:

1. lu eombina-tion with a condenser, a tluid actuated eject-or for withdrawingr noneomlensable gases troni the condenser, a feed water heater'ha'ving an air vent port and an inlet portI through which said ejector diseharges into the heater, and a. single pump tor withdrawing water ot' condensation from the condenser and :l'or delivering 'it with the. fluiddischarged from the. ejector through the. inlet port to mid feed water heater.

2. Apparatus ,for conserving heat, comprising a feedwater heater having an air vent port, a condenser, a steam actuated ejector for withdrawing the noncondensable tiuids from the, condenser, means for delivering the fluids exhausted from the ejector to the heater, a pump tor withdrawing the. water ot eom'tensation from the condenser and means for mixing the Water of condensation with the tluid exhausted from the ejector before. it reaches the heater and for delivering the mixture to the heater.

25. Apparatus for conserving heat, oomprising a condenser, a feed water heater havthe eomlenser, a feed water heater having an' air vent port, a diffuser comunlnicatin with an inlet port of said heater and with t e ex haustr ot the ejector, a water delivery nozzle tor delivering water through the diffuser to the heat-er, and means tor withdrawing water ot condensation from the condenser and for delivering it to said nozzle.

5. .'\.p}luiratus for conserving heat, comprising a condenser, a fiuid actuated ejector t'or withdrawing noneondensable gases from the condenser, a feed water heater having an air vent port, a ditl'usercommunicatin with an inlet port of said heater, a fluid de ive'ry nozzle eonnnnnie-ating with the exhaust of the ejector and projecting into the diffuser, a condensateY pump for withdrawing water of condensation from the condenser, and an ainnula r nozzlev surrounding said Huid delivery -nozzle for delivering water discharged from said pump through said diifuser to said heater.

In testimony whereof, I have hereunt subscribed my name this twelfth day of June, 1915. T
